"I know who I am, kid."

From Arthur Miller's Death of a Salesman:

Biff: I know who I am, kid.
Happy: All right, boy. I'm gonna show you and everybody else that Willy Loman did not die in vain. He had a good dream. It's the only dream you can have--to come out number-one man. He fought it out here, and this is where I'm gonna win it for him.

Cian at 'fuh- 'baw:

"And, we the fans, will begin to believe again that our team can win it all... maybe not this year, fans of Chiefs or Lions will say. But that far flung hope persists.

"Never mind that 16 weeks of nagging injuries, last-second heartache, muddy uniforms, myopic playcalling, etc, etc should tell us different (well, unless you're a Steelers fan). In some compacted version of the American dream, at some point, we will all feel like our team has a chance. (And like the American dream, some will never attain it.)"
